| I have been wanting to try using a tube amp. Looking at the speaker and its specs you'll need a pretty powerful amp, although a lot depends on your room. As far as I can make out (Focal is pretty precious about what specs they are willing to publish), this speaker is four ohms in the bass an... | |
| Purifi Class D: Junk? Show us just one that’s not, and can almost double it’s rms measured wattage from 4ohm to 2ohm. The true indication of not current limiting, like many good A/B bjt amp.George, seriously, you would do yourself well to educate yourself on how amps... | |
| Schiit Freya damage by giving it an electric static discharge on the volume knob. The equipment should be static discharge protected... not saying that it is, but should be (its just a resistor and a capacitor that is needed to protect it; its not rocket science....). Its not like this sort of thing hasn't been known about for ... | |
| Purifi Class D: Junk? Take that as I would as colouration distortions, countering what they say earlier in the same sentence as "The NC500 is practically devoid of any sonic signature ” Actually the two comments sound entirely in agreement with each other. | |
| I have been wanting to try using a tube amp. What loudspeakers are you running? This can have an big effect on the results you get from a tube amp. Generally speaking, a speaker that is 8 ohms or more (particularly in the bass region) and is of reasonable efficiency (+90dB) will show off the... | |
| Purifi Class D: Junk? No they are the output buffers in the rear of the MSB discrete R2R dac, which can swing 7.5v and do it with ease into 2kohm, with no temp rise or voltage drop or heat sink needed into the raw NC500 module Did you test to see if they actually do ... | |
| What aspects of a tube amp/preamp contribute to "holographic" effect on soundstage? There are three things I can think of:1) linearity- this is why triodes and ultralinear are more 3D, because they are more linear2) bandwidth- phase shift can mess with your perception of the soundstage. In tube amps the only way to prevent this i... | |
| Purifi Class D: Junk? No not really, the output buffers have .7ohm output impedance, but use a 50ohm series resistor for protection@georgehifi Are you saying you built a preamp or buffer circuit using these ICs? | |
| Purifi Class D: Junk? @unsound Thanks. There's still a bit of missing information, but you might be able to 4-5 volts out of one of those DACs (balanced), which would certainly be enough to make our module play although you wouldn't be able to drive it to full power. ... | |
| Purifi Class D: Junk? No, it is not, especially with the Hypex amps. The input is meant to be driven by a very low impedance source.In order to make the comparitor work properly (no offsets, no oscillation) with all the comparitors we tried we did wind up with an inpu... | |
| Disappointment with Pass Labs - I'm looking for something else Any amplifier that has a fully balanced design will eliminate all even-ordered harmonics, and thus will be 3rd harmonic dominant. This is what is known as a 'cubic non-linearity' as opposed to the quadratic non-linearity that expresses a dominan... | |
| DEBRA / SWARM DSP? @oldhvymec +1! | |
| What makes tape sound better than vinyl ? Actually, LP can have an edge over tape when it comes to HF, because it's not subject to saturation the way tape is. I'm not sure why you think LP can't produce the full frequency range in wide stereo, but it sounds like you're not using a good... | |
| Best cost no object tube phono I would be interested to know with paralleled tube circuits, how can you ensure the tube sections parallelled are matched, and stay matched over a reasonable time. If they are not perfectly matched, then I would assume smearing of signal occurs... | |
| Distortion/too much bass from turntable If the cartridge is that old, another problem you can have is the cantilever suspension could be perished. This happens with many cartridges and happens whether the cartridge is played or not. If it went soft it would also do as you described. I'd... |
